Question

好的我有以下应用：

babel.cfg

[python: **.py]
[jinja2: **/templates/**.html]
extensions=jinja2.ext.autoescape,jinja2.ext.with_

露/的初始化的.py

babel = Babel()

def create_app(object_name):
  app = Flask(__name__)
  app.config.from_object(object_name)

  app.register_blueprint(main_blueprint)
  app.register_blueprint(category_blueprint)
  app.register_blueprint(item_blueprint)

  babel.init_app(app)
  db.init_app(app)
  return app


@babel.localeselector
def get_locale():
  return 'de'

露/控制器/ main.py

main_blueprint = Blueprint(
    'main',
    __name__,
    template_folder='../templates/main',
)

@main_blueprint.route('/debug')
def debug():
  print get_locale()
  return gettext('A simple string')

我运行了以下命令：

pybabel extract -F babel.cfg -o messages.pot。
pybabel init -i messages.pot -d translations -l de
pybabel compile -d translations /

这就是我的项目结构：

    `-- de
        `-- LC_MESSAGES
            |-- messages.mo
            `-- messages.po

这些是翻译的结果：

当我访问/调试时，我发现我的语言环境是de。但是，我仍然看到A simple string正在输出。有什么想法吗？

Answer 1

对我来说，解决方案是设置BABEL_TRANSLATION_DIRECTORIES变量。它包含一个字符串，其路径以';'分隔。

在我的配置中（只有一个位置）：

BABEL_TRANSLATION_DIRECTORIES ='/ home / work / python / project / translations'

Answer 2

我的答案与fmelan相同，但是我使用绝对路径：

ax.set_xlim(0.0,)

Answer 3

从fmelan的答案扩展：如果您的translations目录与flask_app.py位于同一位置，那么您可以这样做：

app.config['BABEL_TRANSLATION_DIRECTORIES'] = './translations'

...，而不必担心绝对路径是否在应用程序运行的任何地方都可以使用。

对我来说，这很好地解决了将页面部署到PythonAnywhere时的怪异行为。

Flask babel没有简单的翻译工作？
